As you may know, there are tons of great ambiguous illusions. Many include silhouettes but others include pictures in which you can see more than one image depending on how you look at it.
look at the image at the left. What do you see? (there is more than one answer)
When I first looked at an illusion like this, I said that it was a chef holding a giant cake with a piece missing. When I others though, I also go the answer “a piece of cake on a platter”. Can you see both?
I made it easier to see both images by flipping the original illusion.

On the image at the left, you can see a pink cake with a slice removed (the yellow is the inside of the cake).
On the image at the right, you can see a slice of cake on a pink platter (the top of the slice is black).
The nature of ambiguous images allow viewers to interpret and view the same image in more than one way. When viewing the illusion right side up, it is logical to see that a slice is missing because of the orientation of the baker and his hands. When viewing the illusion turned around however, the whole cake becomes a platter that only holds one slice. Because the orientation of the image has changed, you now see another logical explanation for the image.
Other examples of these illusions are:

What do you see in this image?
If you flip the image around you get a whole new interpretation:

Which image did you see first?
Thats all for now,

The second (bird/boat illusion) was taken from The Little Giant Book of Optical Illusions by Keith Kay.
ive always wanted to make on of these. but its so damn hard.
its easy if you know how to use photoshop because they have different shape tools
the cake one was reallly cool
I saw the upside-down bird when I first looked at the second illusion.
Pretty funny, for the first picture I saw trees which turned out to be the birds legs, a fish which turned out to be the head, and a boat which was the beak:)
